You didn't know that? The sixaxis replaced rumble with the motion sensing. In resistence I think motion sensing is only used to shake of chymeras. But the motion sensing will REALLY be used in an upcoming game called Lair when you use the motion sensing to fly on dragons. The best game for the ps3 currently is either Rainbow six vegas or another multi platform game. Since you have a ps3 you're gonna have multiple orgasms this december, by then a shitload of ill games will be out by then.(including gta4 and assasins creed). Look all this shit up on gamefaqs.com
